FIELD OF THE INVENTION

The present invention relates generally to management of energy consuming devices, and more specifically, to a database layer, display layer, and device layer architecture for managing energy consuming devices.

BACKGROUND

Many companies are forced to analyze and manage field device sensor data and energy consumption individually and at a high cost. The standard architecture for such systems causes extremely slow data display, with page switching times of thirty or more seconds, leading to a poor user experience.

Data display may be designed on a site level, as that is where the controls exist, and therefore multi-site data integration may be difficult. User interface (UI) customization tools are usually proprietary and specific to the system installed, resulting in the installing company doing all the UI development and customization for the end user.

Current energy management software systems are often proprietary to the manufacturer's platform. Therefore, once the initial vendor decision is made, users often face high switching costs and cannot easily shop for competitively priced platforms due to system incompatibility.

Extensive and in-depth analysis of energy management data may be time consuming and difficult. Energy analytics may be done by a team of engineers, and may take months from the data generation time to be returned to the user.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated. The present technology provides an efficient, comprehensive solution for monitoring and managing energy consumption in a multi-site segment. The present technology separates controls into three discreet layers: device, data, and display, and is designed to be platform agnostic in all three of these layers.

The present technology provides an improved user experience by displaying user requested data from the database layer, rather than from the field device layer. The average data page may load over ten times as fast as prior art system, which may result in page switching times of less than two seconds. This can be contrasted with more than thirty seconds for other energy management systems.

Easy multi-site integration is provided using the present technology. Because all the data is stored at the database level, there is no inherent need to manipulate this data from a site-centric perspective. This allows much more flexibility and speed in multi-site user displays. This enables a user to look at data in any manner they prefer, rather than simply the way it was gathered.

The present technology also allows for extensive user-interface (UI) customization. Because the UI adheres to web standards, all the modern web graphical user interface (GUI) tools can be applied to create the user experience. The palette of options is much broader with the open tools available to web development than with any proprietary GUI development system.

The present technology also reduces platform switching costs. The present technology is platform agnostic at the device level, and therefore the data and display layers can rest on many different device layers, simultaneously. For example, even with a Cisco mediator in one building and a Trend BCX in another building, the present system seamlessly gives the user the same experience with respect to both buildings. The user can select hardware platforms based on pricing and features, and freely move between options, without changing their user experience.

The present technology also lowers monitoring costs. The database layer allows for a whole new level of logic, separate from controls logic: business logic. Monitoring and analytics, independent from controls, are easily imbedded into the database structure. The turn-around time for analytics in the database may be a few seconds.

The present technology increases technician efficiency. By using currently available software, when dispatched to a site, technicians may be required to contact a central service staff in order to learn what the current energy consumption characteristics are of that particular location. This results in the retail customer paying for two employees—their own technician and the central service personnel. With the present technology, technicians can access instant, current, building-specific data populated via a mobile device or tablet computer, enabling the avoidance of significant wait times and in turn, the reduction of on-site hours.

The present technology provides a Geographic Information System (WebGIS) Mapping, and specifically segments stores or other locations and enabling analyzation of those within user-defined geographic areas. The importance of this functionality lies with the ability to track which stores are consuming above a specified average energy (measured in KwH/ sq. ft.).

The present technology cross-references all sites within the user-defined geographic boundary and highlights buildings that are consuming above average levels of energy with respect to the average usage of the location. Managers can quickly, and in real time, observe and evaluate energy usage across all locations. Outliers can be identified quickly and remotely brought back to the average usage level. Alternatively, if necessary, technicians can be dispatched to the site. If monitored by centralized service personnel, multi-site management can create a significant recurring revenue stream with a high profit margin.

The present technology provides an open architecture and modular software. Each of the layers in the present technology is designed to be platform agnostic.

The present technology is designed from the ground up to be device agnostic. Any controls device that can communicate with another device using Modbus, bacnet, web interface, xml-rpc, or other API can be integrated with the present technology.

The present technology is built on the open standard MySQL database, and has been successfully run on all major server operating systems, including Linux, MacOSX, and Windows.

The present technology displays run with any major web browser, including Chrome, Safari, Firefox, and Internet Explorer. These displays can be on any web-enabled operating system, including PC's, Macs, Ipads, Iphones, Android tablets, Android phones, and netbooks.

The present technology will pull data and aggregate information from multiple hardware manufacturers, and will provide Enterprise level security and user management tools.

The present technology addresses software issues by having the ability to create any type of software application, with minimal development time and cost. The present technology uses the industry standard platforms of MySQL, PHP, and Apache, and includes an extensive, customized MySQL database and large library of PHP code that are not available for viewing or editing by the end user.

The database structure enables management of extremely large volumes of data generated by multi-site control systems. The analytic tools used to convert raw data into user-friendly layouts and formats are embedded in the PHP code library. The complex data extraction tools, or ‘drivers’, needed to access the different field devices are embedded in the PHP code library.

In contrast to the propriety database structure, the data and metrics created by the present technology can be displayed by any of the major web display technologies, including Adobe Flash and the industry standard of HTML5/CSS3/Javascript/Ajax.

The present technology encompasses analytics software for additional appliances including HVAC, boiler and chillers, as well as other applications, including Demand Limiting, mobile device GUI with webGIS to pull data simply by physically being on-site and Demand Response.

A database layer according to the present technology collects and organizes data from many different types of devices. The devices compatible with the database may collect different data including sensor data, output data, and energy consumption, all possibly marked with a timestamp. The data from the different devices may have different data formats and data transmission frequencies. The database layer may include a set of driver modules adapted to communicate with different types of devices. The communication may include commands to change an energy output, increase a data collection frequency, and/or change a control logic.

Controls logic may typically reside in a device controller of an energy consuming device. Alternatively, controls logic may reside in a database, specifically a database computer local to the device. In this case, the server may synchronize with the device's local database computer, and the database layer may therefore be embedded into two or more devices. A multi-device database layer in which the database resides in or directly coupled to device controllers along with a centralized web server database may have a speed and/or data integrity comparable to the system described herein in which the database layer resides only in a centralized web server. Part of the database may thereby be local to a particular energy consuming device, with controls logic for that device residing in that part of the database.

FIG. 1 is a diagram illustrating system 100 according to an exemplary embodiment. System 100 includes display layer 110 in communication with database layer 120. Display layer 110 may be a personal computer, tablet computer, smartphone, or any other appropriate input/output device. Display layer 110 may communicate with database layer 120 over a telephone network, a mobile phone network, the internet, an extranet, an intranet, or any other appropriate network communication system.

Database layer 120 communicates with field device 140, field device 142, field device 144, and sub-system controller 150 through intermediate network 130. Intermediate network 130 may be a telephone network, a mobile phone network, the internet, an extranet, an intranet, or any other appropriate network communication system. Sub-system controller 150 includes field device 160 and field device 162.

FIG. 2 illustrates a computer system according to an exemplary embodiment. Computer 200 may, for example, be display layer 110, database layer 120, or sub-system controller 150. Additionally, computer 200 can perform the steps described herein (e.g., with respect to FIG. 4). Computer 200 contains processor 210 which controls the operation of computer 200 by executing computer program instructions which define such operation, and which may be stored on a computer-readable recording medium. The computer program instructions may be stored in storage 220 (e.g., a magnetic disk, a database) and loaded into memory 230 when execution of the computer program instructions is desired. Thus, the computer operation will be defined by computer program instructions stored in memory 230 and/or storage 220 and computer 200 will be controlled by processor 210 executing the computer program instructions. Computer 200 also includes one or more network interfaces 240 for communicating with other devices, for example other computers, servers, or websites. Network interface 240 may, for example, be a local network, a wireless network, an intranet, or the Internet. Computer 200 also includes input/output 250, which represents devices which allow for user interaction with the computer 200 (e.g., display, keyboard, mouse, speakers, buttons, webcams, etc.). One skilled in the art will recognize that an implementation of an actual computer will contain other components as well, and that FIG. 2 is a high level representation of some of the components of such a computer for illustrative purposes.

Some of the above-described functions may be composed of instructions that are stored on storage media (e.g., computer-readable medium). The instructions may be retrieved and executed by the processor. Some examples of storage media are memory devices, tapes, disks, and the like. The instructions are operational when executed by the processor to direct the processor to operate in accord with the invention.

It is noteworthy that any hardware platform suitable for performing the processing described herein is suitable for use with the invention. The terms “computer-readable storage medium” and “computer-readable storage media” as used herein refer to any medium or media that participate in providing instructions to a CPU for execution. Such media can take many forms, including, but not limited to, non-volatile media, volatile media and transmission media. Non-volatile media include, for example, optical or magnetic disks, such as a fixed disk. Volatile media include dynamic memory, such as system RAM. Transmission media include coaxial cables, copper wire and fiber optics, among others, including the wires that comprise one embodiment of a bus. Transmission media can also take the form of acoustic or light waves, such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, a hard disk, magnetic tape, any other magnetic medium, a CD-ROM disk, digital video disk (DVD), any other optical medium, any other physical medium with patterns of marks or holes, a RAM, a PROM, an EPROM, an EEPROM, a FLASHEPROM, any other memory chip or cartridge, a carrier wave, or any other medium from which a computer can read.

Various forms of computer-readable media may be involved in carrying one or more sequences of one or more instructions to a CPU for execution. A bus carries the data to system RAM, from which a CPU retrieves and executes the instructions. The instructions received by system RAM can optionally be stored on a fixed disk either before or after execution by a CPU.

Database layer 120 may have a redundant web server configuration having one or more of the following features: 1) replicated databases, 2) scheduled backups to provide a second layer of protection in the case of a server crash, 3) redundant server with replication and IP Heartbeat provides for immediate failover and zero loss of data, 4) does not require constant monitoring or support, 5) no human intervention required for failure or recovery, and 6) proven open-source architecture with a long-term track record under sustained loads.

From a web server database, a replicated, redundant web server configuration may be developed using the following steps. First, by deploying a second, identical server and implementing MySQL Master-to-Master replication, a “Hot-Spare” server (also referred to herein as secondary production webserver 306) is provided with data that is only milliseconds behind the primary web server.

The next step in the development is by deploying HeartBeat IP, the two servers can share a common public IP address and all traffic is routed through that public IP. Therefore, when the primary web server fails, the secondary web server takes over the public IP address and handles all of the traffic. For example, if the primary web server fails, within 700 ms, failure is detected, and the public IP is moved and traffic is redirected to the secondary web server. When the primary web server comes back online (either due to reduced load or human intervention), replication resumes. Once replication has caught up and both databases are back in sync, the primary web server may regain control.

The next step in the development implements a content management framework that is database driven, thereby allowing the running code to take advantage of the features provided by MySQL replication and Heartbeat IP. In addition, the framework provides a publishing mechanism, which allows for easy transfer of code from development to production, including rollback and scheduled pushes. By created a separate development environment, the production environment may remain uncorrupted.

The next step in the development provides a staging environment, which encourages the maintenance of an uncorrupted production environment. Finally, database backups are made at each level in the stack to provide a fourth layer of backup at the production level and a third layer of backup at the staging and development level. At any one time, there may be no less than eight copies of the content and code at various stages of production, excluding offline backups. Backups may be performed on the secondary web servers, reducing the load on the primary web server, which is extremely important for large data sets.

FIG. 3 is a diagram illustrating database layer 120 according to an exemplary embodiment. Database layer 120 includes production environment 300, staging environment 340, and development environment 380. Display layer 110 may communicate with production environment 300 of database layer 120 through production public IP address 310. Additionally or alternatively, a field device and/or a sub-system controller including one or more field devices may communicate with production environment 300 of database layer 120 through production public IP address 310.

Production environment 300 may include primary production web server 302, primary production database 304, secondary production web server 306, and secondary production database 308. Primary production web server 302 may bilaterally communicate with secondary production web server 306, and primary production database 304 may bilaterally communicate with secondary production database 308. Secondary production database 308 may communicate with a backup system which may be remotely located to prevent catastrophic loss of data due to failure of both primary production database 304 and secondary production database 308.

Customers may preview or review internally and/or test a new database system in staging environment 340 of database layer 120 through staging public IP address 320.

Development environment 340 may include primary development web server 382, primary development database 384, secondary development web server 386, and secondary development database 388. Primary development web server 382 may bilaterally communicate with secondary development web server 386, and primary development database 384 may bilaterally communicate with secondary development database 388. Secondary development database 388 may communicate with a backup system which may be remotely located to prevent catastrophic loss of data due to failure of both primary development database 384 and secondary development database 388.

Development of a new production environment 300 may start in development environment 340 and progress through staging transition 392 to staging environment 340. From staging environment 340, the development may progress through publishing transition 352 to production environment 300.
